Email routing and delivery options for Google Workspace  |  Gmail  |  Google Workspace Help

As an administrator, you can customize how email is routed, delivered, and stored to meet your organization's needs.

For example, you might have incoming messages sent to an unknown address routed to a specific mailbox. Or, you might want messages addressed to a specific person automatically also sent to another person. You can have some people get their messages in Gmail and other people get email from your on-premise email server. Gmail can also scan inbound message stored on your on-premise server for spam and compliance.

Gmail split delivery lets you deliver incoming email messages to 2 different email systems in your domain, based on recipients you specify. For example, use split delivery when some people in your organization use Gmail and other people use a different email system.

Set up dual delivery when you need to deliver messages to 2 or more inboxes. For example, users can receive messages in a Gmail inbox and another inbox, for example an inbox on an on-premise email server.
